Description
Technical field
The utility model relates to exhaust pipe of engine muffler technical field, specifically a kind of Multistage mufflers.
Background technique
Currently, exhaust pipe of engine muffler be all made of it is a kind of reducing diameter of outlet come by way of carrying out noise reduction,
As shown in Figure 1, this mode is for realizing that acoustic attenuation performance is effective.But eliminated the noise using this structure, it is necessary to make out
The diameter of mouth becomes smaller, and leads to the pressure at expulsion for not adapting to engine, moreover, because the reason of cost and space, it is difficult to use
This mode designs Multistage muffler.
Utility model content
For overcome the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a kind of multistages to disappear
Sound device can realize multistage noise reduction in the case where excessively not reducing exhaust port area, and structure is simple, and manufacturing cost is low.
In order to solve the above technical problems, a kind of Multistage muffler of the utility model the technical solution adopted is that:
A kind of Multistage muffler, including exhaust pipe and the "the" shape baffle assembly being arranged in exhaust pipe, the partition
Component includes at least two partitions, and the periphery of each partition is close to for exhaust pipe being separated into the sealing of the inner wall of exhaust pipe respectively
Several expanding chambers are equipped with a gas vent on each partition to make adjacent expanding chamber be connected to.
It is preferred that the partition is made of elastic material, the angle between the two neighboring partition can adjust so as to
Enough space sizes for changing corresponding expanding chamber.
It is preferred that the space of each expanding chamber is arranged successively from big to small, close to the expanding chamber of the exhaust outlet
Space is minimum.
It is preferred that the gas vent of the two neighboring partition is arranged in a staggered manner.
It is preferred that being additionally provided with an escape pipe, the import of the escape pipe on the partition of the exhaust outlet
It is fixedly connected with the gas vent periphery of the partition, the exhaust outlet of escape pipe is towards the outlet of exhaust pipe for being vented.
It is preferred that the baffle assembly is detachably connected with the exhaust pipe.
It is preferred that being additionally provided with the mounting plate that can be close to the exhaust inside pipe wall on the baffle assembly, mounting plate is equipped with
The tube wall of screw hole, the exhaust pipe is equipped with through-hole, and the baffle assembly can be fixed on exhaust pipe by screw.
It is preferred that the baffle assembly is the "the" shape folded plate formed and by metal plate benging.
The beneficial effect of the utility model Multistage muffler is: passing through the "the" shape baffle assembly being arranged in exhaust pipe
Multiple expansion room type muffler may be implemented；In addition, by changing the angle between adjacent separator, thus it is possible to vary each expanding chamber
Volume to realize adjustable muting function；Since the utility model Multistage muffler can not excessively reduce exhaust outlet face
It eliminates the noise in the case where product, therefore the influence to engine output is smaller；Only gone forward side by side by cutting metal plate in the form of three-dimensional expansion
The "the" shape baffle assembly can be made in row bending machining, and structure is simple, and manufacturing cost is low.
It is described further below with reference to effect of the attached drawing to the design of the utility model, specific structure and generation, with
It is completely understood by the purpose of this utility model, feature and effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of conventional exhaust pipe muffler；
Fig. 2 is a kind of the schematic diagram of the section structure of Multistage muffler of the utility model；
Fig. 3 is a kind of decomposition texture schematic diagram of Multistage muffler of the utility model.
Wherein: exhaust pipe 1, baffle assembly 2, partition 21, gas vent 22, escape pipe 3, mounting plate 4, screw 5.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that saying that the specific embodiment of description is used only for explaining herein
The utility model is not used to limit the utility model.
As Figure 2-3, a kind of Multistage muffler, including exhaust pipe 1 and the "the" shape partition being arranged in exhaust pipe 1
Component 2, the baffle assembly 2 include four partitions 21, the periphery of each partition 21 respectively with the inner wall of exhaust pipe 1 sealing be close to from
And exhaust pipe 1 is separated into three expanding chambers, a gas vent 22 is equipped on each partition 21 to make adjacent expanding chamber be connected to,
The gas vent 22 of the two neighboring partition 21 is arranged in a staggered manner, and the space of each expanding chamber is arranged successively from big to small, close to institute
The expanding chamber space for stating the outlet of exhaust pipe 1 is minimum, as shown in Fig. 2, A, B, C respectively represent the space size of three expanding chambers, A <
B < C.An escape pipe 3, the import of the escape pipe 3 and institute are additionally provided on the partition 21 of the exhaust pipe 1 outlet
22 periphery of gas vent for stating partition 21 is fixedly connected, and the exhaust outlet of escape pipe 3 is towards the outlet of exhaust pipe 1 for being vented.
The baffle assembly 2 is made by cutting metal plate in the form of three-dimensional expansion and carrying out bending machining, two neighboring
Angle between the partition 21 can adjust to change the space size of corresponding expanding chamber.
The baffle assembly 2 is detachably connected with the exhaust pipe 1, it is preferable that is additionally provided with energy on the baffle assembly 2
Enough it is close to the mounting plate 4 of 1 inner wall of exhaust pipe, mounting plate 4 is equipped with screw hole, and the tube wall of the exhaust pipe 1 is equipped with through-hole,
